Re: Scissor-tailed Flycatcher at the Ball fields
At Nestor Park last week we had a pair of Summer Tanagers, Cassin's Vireo. Heading away from the ball field turn left om Hollister, on the right here are community gardens & over the bridge on the right is Bird & Butterfly Gardens, both of these locations we have the Black-throated Magpie Jay.
Here is another place to go that we had some rare Egrets/Herons & a Common Goldeneye. link to map for these: 32°45'14.9"N 117°14'45.5"W
Good Birding!
